In this animated object, learners read about the uses of nanotechnology. The sciences, engineering, electronics, and other disciplines converge in nanotechnology. Examples are given for applications in manufacturing, biomedicine, and environmental science. Concerns about possible environmental effects are discussed.
Weight-Volume Relationships: Introduction to a 3-Phase Diagram
In this animated activity, students read about weight-volume relationships within a given sample of soil or aggregate. They complete problems using a 3-phase diagram.
Statics - Trig: Pythagorean Theorem Calculations Using a TI-86
In this animated and interactive object, the learner uses a TI-86 calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.
In this animated object, learners examine the situation that occurs when any two links of a mechanism lie in the same plane or on a straight line. Crank-sliders and crank-rockers are shown.
Learners examine how a force may be considered to act at any point along its line of action as long as the magnitude and direction of the force remain unchanged. Numerical verification is provided.
